AUXILIARY APPARATUS FOR CONDENSERS.

Application filed April 18, 1922. Serial No. 554,513. j

To all whom it may concern:

Be it known that I, ROBERT SUCZEK, a citizen of the United States, residin in the city and county of Philadelphia, tate of Pennsylvania, have invented certain new and useful Improvements in Auxiliary Apparatus for Condensers, of which the fol lowing is a specification.

My invention relates to apparatus for removing liquid or air, or both, as from regions of lower pressure to higher pressure,

- by ejector action; more particularly, my invention relates to apparatus of the character referred to for removing condensate or air. or both, from a condenser.

My invention resides in apparatus for removing liquid, as condensate, from a receptacle by the ejector action of a motive fluid consisting of components one of which is controllable in response to changes in the quantity of liquid to be removed, and another of which is the discharge of an ejec-r tor which raises the pressure of air or other gas.

My invention resides in other features of structure and combination hereinafter described and claimed.

For an illustration of one of various forms my apparatus may take, reference is to be had to the accompanying drawing, which is a vertical sectional view, some parts in elevation, through apparatus embodying my invention.

Referring to the drawing, 0 represents the body or shell of a condenser, for example, the shell of a surface condenser having'the inlet E for the steam to be condensed, as the exhaust steam from a turbine, steam engine, or from any other source. The steam entering at E is condensed in well known manner into water, which is the condensate which is collected in any suitable receptacle, as, for example, the hot well H. O is a port through which 'air is removed from the interior of the condenser C for producing or maintaining therein high vacuum, as well understood in the art. The port 0 communicates with the suction of the ejector Z, whose nozzle structure n is supplied with motive fluid, as steam or any other suitable motive fluid, through the pipe connection 8.

The ejector Z discharges the mixture of air and motive fluid, as steam, .into the chamsteam, as live or high pressure steam, from the pipe 8 controlled by the valve Y, which is-in turn controlled by the float F on the surface W of the condensate in the hot well or other. receptacle Communicating with the chamber X and extending into the receptacle H is the guide tube or cone B in alignment with the nozzle structure N and in alignment with the diffuser D whose inlet is within the receptacle H and which discharges into the separating chamber L having the air outlet 0 and the condensate outlet The cone or tube B serves as a motive fluid nozzle of a submerged ejector, the motive fluid being thatdelivered by the nozzle N and the discharge from the ejec- .ber X, and the motivefluid jet entrains air and steam from the chamber X and delivers it through the cone or tube B- into the hot well or receptacle H, where condensation of the steam takes place, producing a vacuum which assists the jet from the tube B in drawing condensate from the receptacle H into and forcing it through the diffuser D and delivering the same at higher pressure into the chamber L, where the air separates and is discharged through the passage 0 while the condensate is drawn off through the outlet the condensate in the chamber L overflowing the partition or weir Q, to the discharge outlet As the level W of the condensate falls, the float F falls and moves the Valve Y toward closed position, thereby reducing the amount of steam supplied to the nozzle N, and thereby causing the motive fluid issuing therefrom to remove less condensate from the receptacle H. In case the level W falls far enough, the valve Y will be completely closed. In such case thelow pressure fluid in the chamber X discharged by the ejector Z may alone serve as motive fluid for the submerged nozzle 15 to continue or effect removal of liquid or condensate at low rate. As the level W of the condensate rises again due to accumulation of condensate in the receptacle H, the float F 'will rise and open the valve Y to proper degree.

When the pressure oi the discharge of the ejector Z in the chamber X is sufliciently low while steam is delivered to the nozzle N, the motive fluid of the nozzle N entrains and carries along the fluid from the chamber X. However, 'whenthe pressure in the chamber X due to the discharge from the ejector Z is sufliciently high, it too operates from a low pressure in the receptacle oror cone B, it is supplied with low pressure motive fluid, the same being the exhaust or discharge from the ejector Z, and also higher pressure motive fluid through the nozzle N. The low pressure motive fluid may act alone when the valve Y is closed, or may act in unison with the motive fluid from the nozzle N when the valveY is open; or the discharge from ejector Z may be entrained and impelled by the motive fluid from the nozzle N into the nozzle B, where the mixture of fluids serves asmotive fluid to impel liquid or condensate into the diffuser D, the uncondensable gas or air passing out with the condensate into the chamber L.

In general, the ejector delivers the liquid to a higher pressure; whenthe port 0 is open to atmosphere, the liquid is delivered hot well H to substantially atmospher ic pressure. With the outlet of gas or air from the port O restricted, the pressure in the chamber'L may attain any suitable or desirable degree higher than atmospheric pressure, and the ejector apparatus will deliver the liquid against such higher pressure. In case the low pressure fluid delivered to the chamber X does not contain air or gas, as when low pressure steam from any suitable source is delivered to the chamber X, the

gas draw-ofl port may be omitted, or the chamber L may be omitted and the diffuser D discharge the liquid directly to any region under highpressure, as into 'a boiler.

When the low pressure fluid delivered to the chamber X is alone-acting, as when valve Y is closed, to remove liquid from the receptacle H, the amount of liquid delivered from the receptacle H by the ejector B, D may fall below the requirements,- in which case the lei'elw of the liquid 'will rise and delivered to the chamber X, as from the.

ejector Z, or from any source of exhaust or low pressure steam of variable quantity, the

nozzle structure N will automatically be brought to the assistance of the low pres sure motive fluid and so efl'ect delivery of liquid at the required rate. In other words, thefloat F will take different positions in response to fluctuations in the amount or pressure of the motive fluid delivered to the chamber X and in response also to variations in the amount of liquid required to be withdrawn from the receptacle H.

The float F may control the action of the ejector, as by adjusting an adjustable diffuser, or adjustable nozzle, or both.

While the ejectors herein disclosed are of the simple single'nozzle type, it will be understood that any suitable forms of ejector may be used, as, for example, those employing a plurality of steam or motive fluid .nozzles, or ejectors having annular nozzles and diffusers, .and ejectors of the latter type in which the diffuser is disposed outside of and surrounds the annular nozzle which discharges radially into the diffuser, as disclosed in Letters Patent of the United States No. 1,282,595.
